Novel modified triangular microstrip antenna design obtained by overlapping two triangular-shape patches for angle of 40° further loaded with open circuit stub is presented for achieving circular polarized response in 1200 MHz frequency spectrum. The overlapping between patches and stub yields an optimum spacing between composite patch TM10 and TM01 resonant modes that realize circular polarized axial ratio bandwidth of 71 MHz (5.94%), which completely lies inside impedance bandwidth of above 540 MHz (44%). Across the circular polarized and impedance bandwidth, antenna exhibits broadside radiation pattern showing peak gain of 9 dBi. With above antenna characteristics equivalent design in 900 MHz frequency spectrum can find applications in mobile communication systems.
